STAVE-JOINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 520,873, dated June 5,1894. Application filed June 1, 1893. Serial No, 476,255. (No model.)Patented in England May 23,1893,N0. 10,195. I

To all whom it may concern:

Be it known that I, JOHANN ANTHON, a subject of the Emperor of Germany,residing at Flensburg, Germany, have invented certain new and usefulImprovements in Stave-Jointing Machines, (for which I have obtained apatent in Great Britain, No. 10,195, dated May 23, A. D. 1893,) of whichthe following is a specification.

In the drawings Figure 1, is a sectional view of the apparatus takenlongitudinally. Fig. 1 is a detail view of the pivoted frame in whichthe carriage moves, the rear part of one side of said framebeing'removed to show the interior guide way for the sliding carriage. Fig. 2,is a plan view partly in section on line y-y Fig. 1. Fig. 3, is asection on line 50-00 of Fig. 2,1ooking to the left.

In the drawings is represented a machine in which .the joint is cut bytwo cutters A supported from two bow pieces B B pivoted at their upperends at the point 0 and crossing each other like a pair of scissors. Asthe joint of the stave corresponds to a radial line drawn from thecenter of the cask, the point 0 represents this point and thus the jointis accurately made as the cutters are consequently radii converging topoint C. In order to cut the joint also lengthwise corresponding withthe bilging of the cask, it is necessary that the stave while goingthrough the cutter carriers gets a gradually lifting and loweringmovement. For this purpose thestave is laid on a cast iron frame L,consisting of two small plates, which turn round the pivot L. Betweenthese two plates runs a sliding carriage M shaped like a rack which,lengthened toward the fore part has a tappet N, either fixed or swinginground the pivot O, and below the carriage a pattern P is fixed theretoin any suitable manner to move'therewith. The pivoted tappet enables theoperator to remove the stave readily if desired by throwing down therear end of the tappet and sliding the stave from the carrier table.Operated by the rack and a suitable gearing or otherwise, the. slidingcarriage M, together with the model]? and the stave Z lying on the upperplate M thereof before the tappet N runs forward and pushes, the staveto be jointed through the cutter carriers. The upper plate M isconnected with the carriage M by the part 0%, Fig. 3. By the weight ofthe frame L, swinging around the point L, the model P is pressed uponthe roll Q arranged directly between the cutter carriers. In consequenceof this arrangement the model affects a gradually raising and loweringof the frame L together with the stave lying thereon and at oneoperation the stave gets a larger width on the middle than on the ends,and indeed this difference of the width depends partly on the greater orless angle between the edges of the cutters, partly on the greater orless lowering caused by the shape of the model. Drawn through, the stavedrops from the machinein face of the cutter carriers and the slidingcarriage M being reversed in any suitable way, returns back to itsplace.

In order to prevent undue waste of stufi on both edges and on the middleof the stave while pressed through the cutters, it is necessary that thestave be centered on the frame L and that the cutter carriers can beeasily and quickly adjusted at any distance. For fulfilling theseconditions which render unnecessary a selection of the staves accordingto the breadth the following arrangement will serve.

The bows B of the .cutter carriers rest by means of the pivot E on thetwo equally long rods D turning round the pivot D. These rods arebesides jointed by the rod Gin such a manner that the movement of thepoint E of one bow B corresponds to a quite equal movement of the pointE of the other bow B, of course in an inverted direction.

By a movement of the point E the bows B swinging around the point C arebrought nearer or removed from each other. This movement is effected bythe lever J connected by the rod H with the guide D. The leverin easyreach of the operator, is easily to be stopped at any position by meansof a click catching in the bow K. Lest undue stuff is wasted on bothedges of the stave while going through the cutter carriers, and in orderto be able to center the stave at one operation, two rails S are securedto the frame L. These rails are connected with the frame L by the anglelevers B, one arm of which turns around a pivot of the rails and theothers are by pairs connected by a bar. By these angle levers the railsS get a position parallel to the stave and at the same time a movementremoving and approaching in a paralleldirection. On the rails at acertain distance according to the length of the stave are fixed fingersU, and indeed on the back side two (instead of two can be used also asuitably long rule) and on the fore side only one. These fingers effect,while the rails S are equally moving on toward another, the centering ofthe stave.

In order to center the stave by the lever and at one operation to putthe cutter carriers into a distance suitable to a correct cut,

- it is only necessary that the rails S are connected with the bows B.The connections of the rails S with the bows B are made by catching apin 'Iscrewed to the bow, into the slit of the piece S, fastened toandstanding rectangular to the rail S. While the frame L altogether withthe rails S, is going vertically up and down the pin T slides along theslit of the piece S whereas at a horizontal position of the bows Beffected by the lever, the pin takes the rail S along with it. As Fig. 2shows, each bow B has a pin catching in the slitted piece S.

I claim as my invention 1. In combination, the carriage, the cutters,the bows carrying said cutters, the movable parallel rails S and theslotted plates S and 3. In combination, the cutters, the carriage,

the bows carrying the cutters, the centering rails S arranged parallel,extending longitudinally along the stave and connected with the bows tobe adjusted therewith, the hand lever J, and the connections from saidhand lever to the two bows, substantially as described.

4. In combination, the carriage, the cutters, the bows carrying saidcutters, the movable parallel rails S, the connections between saidrails and the bows to move therewith and the fingers U projectinginwardly from the parallel rails, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
